Yea. First, that "missing beam" is a relx warning, you can ignore it and
it is now a debug message only in recent relx versions.

As for the error message, Jesper is right, it is saying a node with that
name is already running. Maybe you ran a node with 'start' before
running console? If you want to attach to the running node that was
started with 'start' use 'remote_console'
